Ap us politics and gov

can you think of a group or movement that might be threatening to the government or university? should the formation of such a group require government or university approval?

One movement that came to mind for me was the “Black Lives Matter” group and movement. The moment that group was created the government and F.B.I. thought of it as them becoming a security threat. I believe formations of those groups shouldn’t require approval, but rallies or parades should.
